1. A wrench is rotated with torque of magnitude 175 N.m. The force is applied 25 cm from the pivot point, at an angle of 78. What is the magnitude of the force, to one decimal place? 2. Explain why three forces of magnitudes 4N, 5N and 10N can not produce equilibrium. 3. Two forces of 20N and 25N act on an object at angle of 30 to each other. Determine the equilibrant of three forces. Include the diagram.
